COTTONSEEDHULLDELINTING MACHINE.v

Specication ofLetters Patent.

Application filed June 2, 1916. Serial No. 101,329.

To all whom t may concern:

Be it known that I, TOM R. COLE, a citizen of the United States,residing at Rolf, in the county of Pontotoc and State of Oklahoma, haveinvented certain new and useful Improvements inCotton-Seed-Hull-Delinting Machines of which the following is aspecification.

delinting machines, and thevnature and objects thereof will be readilyapparent toV those skilled in the art towhich it apper.

tains in the light of the following explanation of theaccompanyingdrawings, illustrating what I now believe to be the preabrading surface which is formed of diagonal perforations to remove thelint from the hulls in a complete and efficacious manner.V

Another object of the invention is to provide a cotton seed hulldelinting machine having a drum, as mentioned above, and having an areaof circular perforations through which the delinted hulls are ejectedYby means of rubbing surfaces movable in close relation to the perforatedarea.

In addition to the foregoing my invention comprehends improvements inthe details of' construction and arrangementof parts to be' hereinafterdescribed and particularly pointed out in the appended claims.

In the accompanying drawings in which similar and corresponding partsare designated by the same characters of reference throughout theseveral views in which they appear;

. been removed from the cotton-seed during.,`

Fig. 3, is a fragmentary view of a portionof the drum showingthecircular perforations, and

Fig. 4, is a similar view illustrating the diagonal perforations.

After the major portion of the fibers have their passage through thegin, ther-eis foundk to be a mass of'short fibers clinging tothe' hullsof the seeds which it is the object of thismachine to remove. Theseshort fibers when removed and collected are used to a great extent inthemanufacture of nitrated cotton .for which purpose the material is" 1 jpreferable to cottonhaving long fibers. This invention has relation tocotton-seed In machines of this type heretofore constructed thedelinting process was slow and .tedious and consequently the quantity oflint. produced per `unit time was small, which made the cost of theoperation of the ma- 1 chine necessarily high. I proposethereforetoprovide a machine capable of delinting a large quantity of hulls in ashort time, owingr l to the provision of a novel form of abrad# ingsurfacesy against which the hulls are thrown by centrifugal force andengaged by rubbing 'surfaces movable ata high rate of speed. f Y l...

With reference to the drawings 1 indicates an inner drum formedthroughout its length with circumferential abrading formations 2, whichabrading formations comprise diagonally disposed elongated perforations,parallel, and. extended in the same direction. As a result of theseformations and the relation one to another, Ythe effect of thus formingthe perforations is to define a number of broken, spiral groovesextended circumferentially of the drum andfrom end to end. The inneredges of the perforations are sharpened as at 4, and the objects thereofwill be readily apparent as the description proceeds. Y l

An o uter drum 5 is provided for encompassing the inner drum to closethe perforations therein, but is spaced from the discharge end of theinner drum, which discharge end is located at the right-hand side of themachine shown in Fig. 1. The circumferential area of the inner drumuncovered by the outer drum is provided with a plurality of circularperforations 6.

Plates' 7 and 8 are located at the head end and discharge endrespectively of the drum' to form closures for the same to afford asupport for the drum.` The platesY are centrally apertured to formbearings for the shaft 9 which extends longitudinally through the drum,and is also journaled at the discharge end of the drum in a bearing l0.lA pulley 11 is fixed to the shaft between the bearing l() and the endplate 8 whereby the .may be rotated, and a plurality of 'Patented Nov.13, 17,9417. Y

collars 12 are fixed to the shaft, and correspond in number to thenumber of abrad Y ,terminals for engagement with internall threadedsockets in the collars 12, and the outer ends of the arms are formedwith arcuate rubbing surfaces 14; which are disposed for rotation inclose relation to the diagonal perforations. Thus it will be obviousthat owing to the rotative adjustment afforded bv the provision of thethreaded connection between the arms and the collars, the rubbingmembers 14 may be disposed at any desired angle with relation to theangle of the diagonal perforations soas to obtain various degrees ofdelinting effects.

A collar 15 is fixed to the shaft adjacent the discharge end of the drumand is formed with radial arms, an arcuate rubbing surface 16 is formedat the outer ends of the arms for movement in close relation to thecircular perforated area of the drum for a purpose which will bepresently obvious.

An opening 17 is provided at the head end of the drum and at the outerportion thereof for connection with a hopper 18 having journaled thereinan agitator shaft 19 and an agitator 20 mounted upon said shaft. Pulleys21 and 22 are'mounted for rotation upon the shafts 9 and 19 respectivelyand are connected for rot-ation in unison byV means of a belt 23.

An opening 24C is provided in the head plate 7 for establishingconnection between the interior of the drum and the atmosphere, and theextent of said opening is controlled by means of a movable plate The endplate 8 is likewise formed with an opening 26 which is adapted to beplaced in connection with some form of an exhausting or vacuum machineto create a draft of air through the drum, the volume of air fiowingthrough the drum being controllable by the plate 25 mentioned above.

ln operation t-he hulls are fed into the rhopper 18 from which they aredischarged into the interior of the drum then having been set in motion,the hulls are then thrown against the inner surface of the drum bycentrifugal force and abraded against the sharpened edges of thediagonal perforations owing to their' engagement between the surface ofthe drum and the surface of the rubbing members 14. The lint thusgradually and completely removed from the hulls. Owing to the spiral anddiagonal relation of the perforations, the hulls are gradually conveyedtoward the discharge end of the drum, and upon reaching the area ofcircular perforations they are projected or forced through saidperforations by contact with the rubbing members 16 mounted for rotationin close relation to the said perforated area. During the operation ofthe machine the current of air passing through the drum conveys theparticles of lint to a receptacle from which it is subsequentlycollected after a suflicient quantity has accumulated.

lt will be obvious that the delinting effect of the machine may bevaried by adjusting the angle of the rubbing members '-t so as toprovide a shearing action between the edge of the members and thesharpened edges of the perforations, and `the volume of air being passedthrough the drum may be likewise varied to correspond to the delintingof the machine and the speed at which the shaft is rotated.

Various ways of constructing my invention to employ the principlesinvolved will occur to those skilled in the mechanical arts, and Itherefore reserve the right and privilege of changing the form of thedetails of construction or otherwise altering the arrangement of partsWithout departing from the spirit of the invention or the scope of theappended claims.

Having thus described my invention what l claim as new and desire tosecure by Letters Patent is 1. A cotton-seed hull delinting machineincluding in combination a drum having an inner abrading surface, afeeding opening provided at one end of said drum, a plurality ofperforations provided at the other end of the drum, a centrallongitudinal shaft journaled vfor rotation within the drum, rubbingsurfaces movable with the shaft for co-actionwith the abrading surfaces, to abrade the lint from the hulls and to convey the Vdelintedhulls toward the perforated end of the drum, a plurality of arms mountedon the shaft for movement therewith adjacent said perforated end,arcuate members on the arm for movement in close relation to theperforated area of the drum to force the delinted hulls through saidperfor-ations, means for rotating the shaft and means for creating adraft of air through the drum to remove the lint therefrom.
